Question
Everytime i hook up a new cd player in my 99 Cadillac Deville, i can never get the memory to work right. I dont know what im doing wrong. Iv had pros try to hook up new ones and i have the same problem. It keeps memory of last song on cd that was playing but not radio stations, bass, treble and those settings. Help me please if possible!
Hello,
All I can tell you from experience. There are 2 to 3 power sources to the
stereo. One switched power to the stereo for the power antenna, one switched for the stereo itself. 1 constant power for memory. It could be your memory is hooked int switched power. If that is the case, your displlay will work while the key is on and you will lose all your settings as
you are discribing.
You could also have a problem with tge
memory wire or a bad fuse.
If your lighter works on constant power, you should be able to tie your memory power there.
Good luck!

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
